I was just running a passage guide on 1 tim 3.8 and it of course ramped up my laptop pretty ferociously.  
No problem, I'll just click the "stop" button.  And then I noticed: There is no stop button.  
That seems like a pretty strange oversight (or choice).  Am I just missing something?  Is there no way to stop  a report from running?    
Please include a stop button for reports.
